She joins Benedict Cumberbatch, Emma Stone and Charlie Hunnam with Guillermo del Toro set to direct. Plot details are unknown at this time as del Toro and Lucinda Coxon work through a rewrite on a script del Toro and Matthew Robins originally penned.

Legendary will produce and be a participating financing partner on the movie, with Universal Pictures retaining an option to finance at a later date. The film is set to begin shooting in February 2014.

“Crimson Peak” will reteam Chastain with del Toro, who exec produced the horror film “Mama,” in which she starred.

Since receiving an Oscar nomination for her perf in Sony’s “Zero Dark Thirty,” the only other project Chastain had committed to was the adaptation of “Miss Julie.” She had been weighing other projects, including the role of Jane in “Tarzan.” “Tarzan” could still work out, but parts of the deal are still in play.

Chastain can be seen next in “The Disappearance of Eleanor Rigby.” She is repped by CAA and Mosaic.
